UNITED STATES WILLIAM C. MCGILL, OF CINCINNATI, OHIO.

IMPROVED FLuR-YSIFTER.

Specification forming part of Letters Patent No. 54.575, dated May 8, 1866.

To all 'whom it may concern:

Be it known that I, WILLIAM C. MOGILL, ot' Cincinnati, Hamilton county, Ohio, have invented a new and useful Flour'Sifter; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawings, makin g part ofthis specification.

My invention relates to a provision for the rapid sifting of iiour or meal for domestic use, comprising` a pairof sweeps or Scrapers adapted to ,be rotated continuously over a suitable sieve confined within a close box or hopper, which may be set upon the pastry-board or table on which the viands are to be prepared, thus avoiding Wastage, dust, Sac.

Figure l is a perspective view of a sitter embodying niyiinprovements. Fig.2 isa plan ot the Scrapers.

A is a box or hopper in the form of a cylinder or inverted conic frustrum, which may be open at looth ends.

B is a sieve of wire-gauze or other suit-able material. C is a shaft supported at the axis of the hopper in bridges D and D', and having a horizontal arm, E, from Whose under side there project springs F. To the lower ends of the springs F, I attach in an oblique position two blades,G G', of trapezoidal forni, their acute angles g g projecting past the shaft and in front thereof in the manner represent ed, so as to completely sweep the entire surface of the sieve.

By making the arln E of the peculiar forni represented its elasticity is added to that ot' the springs, and it also serves to agita-te and loosen the Ilonr or inea-l preparatory to the action of the blades or scrapers G G.

The upper end of the shaft C terminates in a crank or handle, c.

I claim herein as new and of my invention- In the described combination with the box l or case A and sieve B, the scrapers G g Gr g', springs F, elastic arm E, shaft C, and crank c, arranged and operating substantially as and for thepurpose herein set forth.

In testimony ot' which invention I hereunto set my hand.

\V. C. MCGILL.
